[hpsdr] [CASMIR] Design Thoughts

[Lyle Johnson]

Hello Alex!

> Some initial thoughts on CASMIR. I am thinking of using:
> 
> DDS                  - either a pair of AD9911's (based on availability) or an AD9958
> HF/6m/4m/1.25m/70cm  -  DDS with the ADL5390 out via an SMA connector
> 33cm/23cm/13cm       - DDS with the AD8349 Modulator out via an SMA connector
> 3GHz/5GHz            - still working on it but the TI TRF2436 looks interesting
> 10GHz +              - TBD connector for I/Q Output for high microwave or remoting modulator circuits/amplifiers
> 
> I'll put into a picture later this weekend, but I'd like some gut feelings from the group.

I'd sure like to see something other than a DDS, especially for HF use.
